So, this is kinda similar to the other I helped you with:

<span>So r is the radius of the disk. The area is known and equal to 100Pi; so 

100Pi = Pi r2

Now for r: r = 10 

Circumference = 2 PI r = 20 Pi

I hope this helped!</span>

finlep [7]
(n-2) × 180<span>° = 4 x 180 = 720
so sum of interior angles = 720
x = 720 - (112+133+128+ 100+120) 
x = 720 - 593
x = 127

answer
x = 127</span>

2) <br> 8q+6=4q-14<br> What is The answer ?
Charra [1.4K]

Answer:

q=-5

Step-by-step explanation:

8q+6=4q-14

Remove q from one side

8q+6=4q-14

-4q    -4q

4q+6=-14

Remove 6 from both sides

4q+6=-14

    -6   -6

4q=-20

Divide 4 to isolate q

4q/4=-20/4

q=-5
